I noticed that xml sitemap generator generates ror.xml in utf8. But he also automatically assumes all sites are in utf8 and it doesn't do conversion (or it does but it's wrong?). I have sites running iso8859-2, and that completely renders ror.xml useless. Target encoding could be handled via settings or by parsing html header encoding, and then eventually converted with lib_iconv

Other question I have is - I am not sure what ror.xml is used for? I tried adding ror.xml sitemap to google sitemaps but google reported error.
